'UNITED vs'lr'a'rlss This invention relates to lubricators, for railway journal boxes and the like and is fully described in the following specification and shown in the accompanyingdrawings,

in which:

Figure 1 is a longitudinal vertical section on the line 1 of Fig. 2; i

Fig. 2 is a transverse section on the line 2 of Fig. l;

Fig. 3 is a perspective view of the. lubricator removed from the journal box; and

Fig. 4 is a view similar to Fig. 2 but yshowing a journal box with the lubricator cast integral therewith.

The embodiment sho-wn in Figs.` 1 to 3 comprise a journal box 10 of a well known type adapted to receive the usual brass bearing 11 which rests upon the top of the ournal 12.

It has heretofore been customary to iill the bottom of the jo-urnal box 10 with waste and grease, the waste exten-ding up into contact with the bottom and sides of the journal 12 so that a film of lubricant is continuously supplied to the journal 12 as it rotates. The

present invention aims to supply this lubrication with a much more uniform coat of lubricant and to do so more thoroughly and efficiently.

To do this I have provided a separate lubricant receptacle 13 which is preferably made of sheet metal and which in cross-section is of a generally V-shape. The upper ends of the sides 14 and 15 extend somewhat away from the journal 12 as shown in Fig. 1 and provide spaces 16 and 17 which are wider at the top than at the bottom and which are still more narrowed at the bottom by means of inwardly extending portions 18 and 19 which provide constricted sections 2O and 21.

Waste or the like placed between the journal 12 and the side 14 will have a slight tendency to move down toward the restricted portion 20 as the journal 12 is rotate-d in a counterclockwise direction. Likewise waste lying r beneath the journal 12 will have a tendency to be carried up by this same counterclockwise direction and be wedged against the journal by the constriction 21. A movement of the journal 12 in a clockwise direction will also have the tendency to move the waste in the space 17 downwardly and to wedge it` against the journal in the constriction 21. i A pin'22'is carried by-'the bottomlof thejournal box, engages a recess 23 in the bottom' of the lubricant receptacle and preventsmovementl 5,5f of the receptacle. H Y

`Thus it will be seen that a very simple and convenient lubricator is provided for railway i journal boxes of this type and one which provides a receptacle 13 beneath the bearing for 60; oil solfthat'dirt and moisture in the bottom of the' journal box `will be largely excluded` from the oil in the receptacle.` y The receptacle may lie-introduced into the journal box through the journal-'box cover24 which is re- 65 movable ina Vwell known manner" about the'y hingepin25. j

f The lubricator shown in Figs. ,1' to 3 is that which" is designed for use with railway journals now inservice. In manufacturing new journal boxes however it maybe desirp able to make this an integral part of the boxand this is accomplished lby casting the VoilY receptacle 26 and the sides l27 and `28 integralf as shown in Fig. 4."4r The box isthen filled with waste and 'the like and a suitable lubricant, preferably oil, ispoured over this waste and runs down intoth'e receptacle-26 wliere it passes by capillary attraction to all parts of the waste above it. Of course, a spring 8.0' supported felt pad, or the like, such as is commonly used in journal boxes, may be employed instead of the waste or in addition thereto.

It will be observed that the sides 27 and 28 8.5. not only serve as retaining members for supporting the lubricant containing material, but also serve as vbracing" members which directly buttress the bottom-of the journalbox. Thus, independent of the lubricating means '99 disclosed, the side walls 27 and 28I serve to protect or reinforce the bottom or iioor of the journal box, when pressure is exerted thereon. This advantage is particularly useful when the journal` box is lifted or raised for the purpose of removing or= inserting bearings within the box. It is a well known practice when removing or inserting bearings in this manner to place a jack or lifting member directly below the iioor of the journal box, thus exerting great pressure upon the ioor or bottom of the journal box. Members 27 and 28, as more clearly shown in Fig.

4, serve to protectV and reinforce the'floor of the box during this operation.

The vibration of the axle and journal box causes the waste or packing to settle gradually into the lowerportons of the spaces 16 and 17 thereby causing it to hug the journal more tightly.

v The end walls of the receptacle lie just` beneath the journal so' that the oil level can be kept quite close to the' bottom of the journal. distance to the point'where it is applied to the journal.

IVhile I have shown and described but a single embodiment of thisinvention, itis to be understood that it is capable of may modifications. Changes therefore in the construction and arrangement may be made which do not depart from the spirit and scopeof the invention kas disclosed in the appended claims.

I claim: v

1. In a device of the character set forth, a;

railway journal box, provided with bottom and side walls, interior inclined wallsV c0n necting the 'bottom wall and side walls vof said journal'box, andend wall members con-- necting .the lower portion of saidainterior walls so as toform therewith a lubricantl compartment below the journal.

2. In a device of the character set forth, a railway ournal box, a removable lubricant receptacle adapted to coniine therein a body` ooil and adapted to be placed within said box,said receptacle being provided with walls approaching said journal and being provided with end Walls adapted to stand below said journal, and means for securingsaid receptacle in position belowsaid journal.

vIn testimony whereof I have hereunto -set my hand this k20th day of March, 1928.
